Application filed July 10, 1925.

rllhis present descriptive specification reters to attachahle bladesWhich, through ,their special shape and construction, can be applied tothe different types or, non-skid chain devices, such as those at presentadopted for automobile tyres, to enable them to cross easily boggj,sandy or snowy places.

ris Will be seen further on, the blade which constitutes my invention ischaracterized by the form of the projection which rises from the centralpart of the plate forming tl e base.

rlhis projecting blade has 'an angular notch in one end, which notch iscombined with tivo lateral protuberances, the most salient paris otwhich remain at a certain distance from the base, and the purpose otwhich is to hold fast the hook or link ot the chain through which theend oic the blade has been passer., the chain having previously beenplaced Within the notch.

Although it can be very easily detached, the blade, which is the objectot this present application, keeps so firmly attached that it is notliable to be lost, however rough be the Work to which it is submitted.

To make this description more clear, drawings are attached as followszFig, l shows in perspective a blade manufactured in accordance With myinvention.

Fig. 2 is a drawing in plan ot one ofsaid blades litted to an ordinarychain.

stamped and suitably drawn out; or it may be cast, forged ormanufactured by any suitable method. The lateral protuberances areformed in the blade, and these are to hold the link through Which theblade is 40 passed. The blade has a notch made in combination with theseprotuberances, by means or" which the hooking link can easily beattached, Which link usually joins the circumferential chains With theaxial ones.

Having thus described and specilied the character of my invention, andthe method of applying it, l claim as my exclusive invention andproperty j l. An attachment for non-skid chains, comprising a platehaving a blade projecting centrally from its outer face, said bladehaving a notch in one end and provided adjacent its other end With aprojection on each side, the blade being adapted to be passed through alink of a transverse chain With the projections above the link and Witha circumferential chain lying in the notch thereof.

2. An attachment for non-skid chains, comprising a plate having `a bladeprojecting 'from its outer face, said blade having an angular notch inone end and provided adjacent its other end with projections on itssides, the projections gradually increasing in thickness inwardly andterminating a short distance trom the plate.
